Common Information
TASK 71-00-00-700-060-A00 Procedure After The Use Of Dry Chemical Fire Extinguishing Agents, Testing-000
Procedure After the Use of Dry Chemical Fire Extinguishing Agents
Procedure
As soon as possible after the use of a dry chemical fire extinguishing agent, make sure that the rotors turn freely.
Dry motor the engine at more than 2500 N2 RPM until the EGT decreases below 482 deg F (250 deg C) or for two minutes, whichever occurs first. This is necessary to decrease the gas path temperature and to blow remaining dry chemical from the engine. Refer to TASK 71-00-00-700-001 (TESTING-001).
If you cannot motor the engine, disassemble and clean it as soon as possible. This will keep corrosion off the parts and contamination of the oil system to a minimum.
NOTE
It is not possible to remove all signs of dry chemical agents without engine disassembly.
NOTE
Removal and disassembly of the hot section only is permitted when contamination is limited to the hot section.
